摘要

Flexible pipe, connected with a connecting structure for a flexible tube, wherein said connecting structure comprises a body part and a connecting part, which has a smaller thickness than the thickness of the body part, wherein a first end region in the connecting part is inserted and welded thereto and a heel by a step between the carcass part and the connecting part is formed. A process for the connection of a connecting structure for a flexible tube with a flexible tube comprises a filler metal deposition step of applying a filler metal at least either to a first end region of the flexible tube with ribs and depressions, or to a connecting part of a connecting structure for a flexible tube, in which the first end region is to be used, an insertion of the flexible tube, comprising the insertion of the first end region of the flexible tube in the insert of the connecting structure for a flexible tube, so that the first end region is held by a shoulder on the connecting structure for the flexible tube is formed, as well as a welding step, the flexible tube, comprising the heating of at least a portion of the flexible tube, which in the connecting structure for the flexible tube is used, in such a way that the first end region of the flexible tube with the connecting structure for the flexible tube is welded by the filler metal.
